SLICING-MACHINE.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed. May 29, 1906. Serial Nb. 319,326.

To all whom it may concern:

.Be it known that I, LOUIS E. citizen of the United States, residing atHonolulu, county of Oahu, Territory of Hawaii, have invented a new anduseful SlicingrMachine, of which the following is a specification.

My invention relates to improvements in machines for slicing fruit andthe like, particularly ineapples, in which the fruit is being forcedagainst a plurality of stationary knives.

The object of my improvements is to roduce a machine of this characterwhich is automatic, ra )id and efficient in operation. I accomplishthese objects by the mechanism illustrated in the accompanying drawing,in which Figure 1 is a side elevation of the machine; Fig. 2 is a planview thereof with the blades removed; and Fig. 3 is an isometric view ofa cross-bar.

Similar characters ARNOLD, a

of reference indicate corresponding parts in the several views.

The frame .1 is inclined to the horizontal and is supported b the base2, to which it is bolted by the bolts 3. Guides 4, 5 areattached to theframe 1, and the sides of the block 6 are grooved to receive the saidguides 4, 5 and slide thereon. The front end 6 of the block 6 is curvedto fit the eeled and sized fruit. A rocker-arm 7 is, eyed to a shaft 8mounted in the bosses 9, 10 near the bottom of opposite sides of thebase 2. The provided with set-collars 11. Links 12 connect the up er endof the rockerarm 7 with the rear enc 6 of the block 6 by the pins 13 and14 respectively. A gear 15 is secured to the shaft 16 journaled in thebox 17 in the side of the base 2. The gear 15 is provided with acrank-pin 18. A brass block 19 fits over the crank-pin 18 and slideswithin the slotted portion of the rocker-arm 7. A shaft'20 is journaledin boxes 21, 22 in l the sides of the base 2, and is provided with theinion 23 meshing with the gear 15. The sha t is also provided with atight and a loose pulley, 24 and25 respectively, outside of the base ofthe machine, and with a setcollar 28. The slotted ortionof the rockerarm7 is stiffened by distance pipes 26 between the lugs 7 a and boltsv 27through said lugs and distance-pipes.

A cross-bar 30 is bolted by the bolts 31 to the sides of and below theforward end of the frame 1. A similar cross-bar 32 is bolted by thebolts '33 to the raised sides 1" of the frame 1. These bars 30, 32 areprovided with slots 30*, 32 respectively, in which are placed aplurality of small bars 34. One end of each bar 34 is threaded andprovided with a nut 35, and the other end is provided with a pin 34. Theends of a knife blade 36 are hooked on the pins 34 of each correspondingpair of bars 34in the slots 30 and 32. The blades 36 are similar tohack-saw blades with a knife edge in lieu of teeth. These blades 36 assthrough slots 1 in the frame -1 at its ront end, with their cuttingedges downward. Tension on the blades 36 is obtained by tightening thenuts 35. It will be noted that the blades 36 lie in vertical parallelplanes, and that their cutting edges are inclined about 30 de rees tothe plane of the frame 1. The bloc 6 is slotted to clear the blades 36when the former is in its forward position. A plate 37 is attached tothe top of the block 6 and rojects rearwardly from same. A curved p ate38 is attached to the front end of the frame 1 and above the crossbar30.

In operation, starting from the position shown 1n Fig. 1, the peeled andsized fruit rolls down a chute above the machine and encounters theplate 37. The belt, connecting withany suitable source of ower, beingnow shifted from the loose pul ey 25 to the tight pulley 24, the gear 15carrying the crank-pin. 18 is revolved, thereby causing the rocker-arm 7to swing rearward, drawing with it the block 6 which slides on theguides 4 and 5. The fruit rolls on the late 37 and on the top of theblock 6 until the rear position of said block 6 is reached, whereuponone fruit drops upon the frame 1 in front of the block 6, and is enga edby the curved front end 6 of said blocas it now moves forward.Continuing forward, this fruit encounters the blades 36 and is therebsliced, a shearing cut being effected. The s ices are pushed over thecurved plate 38 and dro onto a conveyor (not shown) by which they aredelivered to the sorters and packers.

The uice runs down the central portion of the frame 1, and is caught bya trough under the lower edge of same (not shown.)

I claim:

1. An improved slicing machine having in combination an inclinedframe-work having a series of parallel slots at its front end, two crossbars extending parallel witheach other and spaced apart and arranged indifferent above said slots, a corresponding tension of the cutters mayinclined, the forward end of said vertical planes, a series of blades orcutters upwardly provided with parallel longituextending between thecross bars having I frame being y their opposite ends connected to thelatter, dinal slots, a feed chute connecting with said one of said crossbar's being disposed below frame, a plunger reciprocable in the ,frameand the other above the plane of said slots l and beneath the deliveryend of the feed whereby intermediate portions of the blades\ chute, saidplunger having an extension extend through the slots, means for feedingl forming a e bottom for said chute material to said blades and meansfor regui whereby the extension supports the fruit and lating thetension of said blades. allows the same to dro 1nto the range of 2. Anirn roved slicing machine including action of the plunger w en thelatter is rean inclined rame-work having parallel longitracted until itsfront end uncovers the end tudinal slots formed in its front end, across of the chute, a series of parallel longitudibar fixed in the upperportion of said frame l nallyextending blades inclined relative to crossbar the inclination of the frame, said blades exfixed to the front endof the frame below said i tending through said slots, a cross bar in theslots, blades or cutters extending at an anupper portion of the frame, asecond cross gle to the inclined frame-work and passing bar in the frontof the frame below said slots, through said slots, bars at the ends ofthe bars connected to the ends of the blades or cutters extendinglongitudinally in line therecutters and extending throughthe cross barswith, said last-named bars extending through and forming longitudinalextensions of said the crossbars and having means whereby the '3 blades,and means cooperating with the lastbe adjusted, and named bars and thecross bars for regulating a block or plunger reciprocable within said ithe tension of the blades. frame-work adapted to feed the material to becut beneath said cutters. l 3.
